Abstract (en)
[origin: WO2021001085A1] An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS. In some cases, the apparatus exploits a probe on a device to generate traffic for learning flow characteristics not obtained from monitoring application IP flows in the network. Embodiments disclosed herein can be used to predict quality metrics for many applications where jitter/latency is a factor affecting perceived quality, such as QoE for a human consumer or QoS for machine type communications. The embodiments are applicable to the analysis of traffic carrying conversational speech.
